Basic functionality of user device 100 may be provided by an operating system 115 contained in memory 100. Various programmed software applications may be executed by utilizing the computing resources in user device 100. Applications stored in memory 110 may be executed by processor 105 (e.g., a central processing unit or digital signal processor) under the auspices of operating system 115. For example, processor 105 may be configured to execute applications such as web browsing applications, email applications, instant messaging applications, and/or other applications capable of receiving and/or providing data.
Data provided as input to and generated as output from the application(s) may be stored in memory 110 and read by processor 105 from memory 110 as needed during the course of application program execution. Input data may be data stored in memory 110 by a secondary application or other source, either internal or external to user device 100, or possibly anticipated by the application and thus created with the application program at the time it was generated as a software application program. Data may be received via any of a plurality of communication ports 120(A)-(C) of user device 100. Communication ports 120(A)-(C) may allow user device 100 to communicate with other devices, and may comprise components such as an Ethernet network adapter, a modem, and/or a wireless network connectivity interface. For example, the wireless network connectivity interface may comprise one and/or more of a PCI (Peripheral Component Interconnect) card, USB (Universal Serial Bus) interface, PCMCIA (Personal Computer Memory Card International Association) card, SDIO (Secure Digital Input-Output) card, NewCard, Cardbus, a modem, a wireless radio transceiver, and/or the like.
User device 100 may also receive data as user input via an input component 125, such as a keyboard, a mouse, a pen, a stylus, a sound input device, a touch input device, a capture device, etc. A capture device may be operative to record user(s) and capture spoken words, motions and/or gestures, such as with a camera and/or microphone. The capture device may comprise any speech and/or motion detection device capable of detecting the speech and/or actions of the user(s).
Data generated by applications may be stored in memory 110 by the processor 105 during the course of application program execution. Data may be provided to the user during application program execution by means of a display 130. Consistent with embodiments of this disclosure, display 130 may comprise an integrated display screen and/or an output port coupled to an external display screen.
Memory 110 may also comprise a platform library 140. Platform library 140 may comprise a collection of functionality useful to multiple applications, such as may be provided by an application programming interface (API) to a software development kit (SDK). These utilities may be accessed by applications as necessary so that each application does not have to contain these utilities thus allowing for memory consumption savings and a consistent user interface.
Furthermore, embodiments of this disclosure may be practiced in conjunction with a graphics library, other operating systems, or any other application program and is not limited to any particular application or system. The devices described with respect to the Figures may have additional features or functionality. For example, user device 100 may also include additional data storage devices (removable and/or non-removable) such as, for example, magnetic disks, optical disks, or tape (not shown).
User device 100 may store device and/or user-specific information in a data store 150, such as a device profile and/or a plurality of user preferences. A device profile may comprise an indication of the current position of user device 100 and/or indications of the hardware, software, and security attributes that describe user device 100. For instance, the device profile may represent hardware specifications of user device 100, version and configuration information of various software program and hardware components installed on user device 100, data transmission protocols enabled on user device 100, version and usage information of various resources stored on user device 100, and/or any other attributes associated with the state of user device 100. The device profile may further comprise data indicating a date of last virus scan of user device 100, a date of last access by an IT representative, a date of last service by the IT representative, and/or any other data indicating maintenance and usage of user device 100. Furthermore, the device profile may comprise indications of the past behavior of associated users, such as resources accessed, charges for resources accessed, and the inventory accessed from such resources. The user preferences may comprise a listing of factors that may affect the experience of the user. In particular, the user preferences may include indications of the user's age, gender, bodily traits, preferred resource types, preferred resources, and combinations thereof.
The application store 210 may comprise a digital distribution platform for application software, often provided as a component of an operating system on a personal computer, smartphone, or tablet. Application stores typically take the form of an online store, where users can browse through different categories and genres of applications (e.g., productivity, multimedia, games, etc.), view information and reviews of then, purchase it (if necessary), and then download and install the application on their device.
The compliance server may comprise a rules store 230 comprising a plurality of compliance rules that may be applicable to user device 100. Attempts by user device 100 to access various resources on user device 100 or located remotely, such as at application store 210, may require user device 100 to be in compliance with one and/or more of the compliance rules.
Depending on the sensitivity of a given resource, different compliance rules may be necessary to ensure that the resource is adequately protected. Some resources may only require ensuring that the proper user is requesting the resource. Other resources may require compliance with more stringent authorization rules, such as determining whether an appropriate transport protocol is used (i.e., http and/or https) by the requesting device, determining whether access to the resource is permitted for a specified duration or at a given time, determining whether the resource is accessed from a secured device, etc. The compliance server 220 may be operative to determine whether a pairing of the user device 100 and a specific user of user device 100 are authorized to communicate with various resources based at least in part on the compliance rules.
In some embodiments, the compliance rules may comprise application white lists comprising a listing of applications allowed to be installed and/or executed on user device 100. The compliance rules may comprise application black lists comprising a listing of applications forbidden to be installed and/or executed on user device 100. Furthermore, the compliance rules may comprise a list of functions, such as those provided by APIs associated with operating system 115 and/or platform library 140, that may be treated as protected functions. Calls to these functions, such as calls to retrieve login credentials, may result in checks for compliance with the compliance rules.
The network 240 may comprise, for example, any type of wired and/or wireless network such as a wireless local area network (WLAN), a wireless wide area network (WWAN), Ethernet, fiber-optic network, and/or any other type of wired and/or wireless network now known or later developed. Additionally, the network 110 may be or include the Internet, intranets, extranets, microwave networks, satellite communications, cellular systems, PCS, infrared communications, global area networks, or other suitable networks, etc., or any combination of such networks.
From stage 310, method 300 may advance to stage 320 where user device 100 may determine whether the application comprises a restricted application or “malware”. As used herein, the terms malicious application and malware may comprise software used to disrupt computer or device operation, gather sensitive information, perform prohibited actions on user device 100, or gain access to private computer systems. Restricted software may encompass malware and/or applications controlled and/or blocked by an administrative or security policy. An application may be determined to comprise restricted software, for example, by determining that the application is on a pre-defined blacklist of applications, by determining which permissions the app seeks from the operating system 115, as certain permissions are not normally required by and/or accessible to apps, and/or by comparing a data payload associated with the app with a plurality of profiles known to indicate that an app comprises restricted software. Such data payloads may comprise, for example, a website address, author, title, email address, icon, text, user interface layout, function calls, and numerous other characteristics associated with applications. Malware applications may also be identified according to static analysis of the application's binary file, such as looking for suspicious function calls or patterns of data access, and/or dynamic analysis during execution of the application on the device and/or on a test, sandbox, and/or emulator environment. Information about the application may be retrieved from remote sources such as compliance server 220 and/or from a 3rd party service that tracks and identifies malicious applications. In some embodiments, user device 100 may provide information about the app to a remote source and receive a determination as to whether the app comprises a restricted application.
If the application is determined to comprise restricted software at stage 320, method 300 may advance to stage 325 where user device 100 may identify at least one action to be performed. For example, upon first identifying the application as restricted, user device 100 may identify a compliance rule associated with notifying the user. If the app continues to be executed or stored on user device 100, or if the user persists in trying to install the app, further actions may be identified by the compliance rules. In some embodiments, these further actions may comprise escalations in their impact upon the user and/or the operation of user device 100. The at least one action to be performed may be based at least in part upon a threat level associated with the triggered compliance rule. For example, a compliance rule may simply prevent operation of a restricted app with a low threat level while another compliance rule may require removal of a medium threat level restricted app and yet another compliance rule may delete sensitive data when a high threat level restricted app is detected.
From stage 325, method 300 may advance to stage 330, where user device 100 may perform the identified action. For example, user device 100 may display a notification to a user that the application is restricted and suggest an appropriate course of action, such as uninstalling the app. User device 100 may notify the user that continuing to attempt to install, execute, or store the application on user device 100 may result in additional actions taken in accordance with a compliance rule. For example, if the app is not removed within 24 hours, access to network resources such as e-mail, web pages, etc. may be revoked. For other examples, data stored on user device may be removed and/or the device may be restored to a factory default state. Further examples may comprise limiting access to other apps and/or hardware functionality on user device 100 until the restricted app is removed and/or disabled. In some embodiments, the compliance rules may cause the user device 100 to remove the malicious application automatically, without user intervention.
If the application is determined not to comprise a restricted application at stage 320, method 300 may advance to stage 340, where user device 100 may designate the app as clean. Such a designation may be used in periodic rescans of the apps to skip apps that are known to not comprise restricted software. In some embodiments, the clean designation may be revoked upon receiving a new compliance rule or if the app is updated. Method 300 may then end at stage 355.
